The announcement was made by Jennifer Salke, president of NBC Entertainment.

“On the verge of our 2013 fall scheduling decisions, we’re pleased to renew five drama series that will be important to our new season line-up,” Salke said. “We’re proud and very appreciative of all of the actors, producers, writers and directors who work so hard to deliver such high-quality work week in and week out. These complex shows represent a broad range of genres and tones, and all of them stand out for us in a television landscape now filled with one-hour series. We’re especially pleased to be renewing “Revolution” and “Chicago Fire” — two first-season successes — and there will be more returning series announcements made in the next couple of weeks.”
